At the moment we have about 200 million gallons of surplus soy oil per year and about 3 BILLION gallons of waste fryer oil per year that could be used for BioDiesel. It isn't enough to displace all of our imported oil by a long shot, so... people ask "After you've used all of that for BioDiesel...what then?".
Here is a great site discussing how BioDiesel could replace ALL of our imported oil someday.
Widescale Biodiesel Production from Algae
Plus...here is a nice comparison of BioDiesel vs. Hydrogen
BioDiesel vs. Hydrogen
Notice that it would cost 169 billion dollars to produce enough biodiesel for all of our fuel needs...but it would take 2500 billion dollars to create enough clean electricity from wind to generate enough hydrogen for our fuel needs.
